Chapter 2 Rack Cabling References ◊ available in either 208 VAC or 230/240 VAC configurations for international markets ◊ Uninterruptible Power Supply (UPS) models rated at 3000 Watts are available for either voltage range; or a 2250 Watt UPS is available for 230/240 VAC (see Table 2-1) ◊ for both 208 and 230/240 voltages, two wide range Power Distribution Unit (PDU) models (rated 10 A and 16 A) are available (see Figure 2-1) ◊ one or more PDUs can be used in each rack enclosure, depending upon requirements for power, current, and number of receptacles (see Table 2-4) Power Cables and Components Available When components are installed in a rack, a power supply subsytem for the rack is required. HP recommends the NetServer LXr 8500 be connected as follows: • connected to a Power Distribution Unit (PDU)--see Figure 2-1. • through an Uninterrupible Power Supply (UPS)--see Table 2-1 • to a properly protected branch circuit or circuits--see "Site Preparation-- Circuit Breakers" in Chapter 1 NOTE A Redundant Switch is available for use between the UPS and the branch circuit or between the PDU and the branch circuit. More information is listed in Table 2-2 and in Appendix B. Table 2-2 lists details of the cables, components, plugs and receptacles for the two rack power supply subsystems for the HP NetServer LXr 8500. Table 2-1.
